- Abstract: Light-matter coupling in a planar optical cavity substantially modifies the
transport regimes in the system in presence of a short range excitonic
disorder. Basing on Master equation for a resonantly coupled exciton-photon
system, and treating disorder scattering in the Born-Markov approximation we
demonstrate the onset of ballistic and diffusive transport regimes in the
limits of weak and strong disorder respectively. We show that transport
parameters governing the crossover between these two regimes strongly depend on
the parameters characterizing light-matter coupling, in particular Rabi energy
and detuning between excitonic and photonic modes. The presented theory agrees
with recent experimental data on transport in disordered organic microcavities.

We study theoretically an array of two-level qubits moving relative to a one-dimensional waveguide.
When the frequency of this motion approaches twice the qubit resonance frequency, it induces parametric generation of photons and excitation of the qubits.
We develop a comprehensive general theoretical framework that incorporates both perturbative diagrammatic techniques and a rigorous master-equation approach.

metastable density structures that suppress emission into one cavity mode prevent relaxation to the stationary, superradiant grating.
We reproduce these dynamics by a quantum mean field model, suggesting that subradiance shares characteristics with quasi-stationary states predicted in other long-range interacting systems.

We show how light is efficiently transported inside such a microcavity, mediated by incoherent absorption and emission processes.
In particular, we show that there exist two distinct regimes of transport, viz. conductive and localized.
We observe that while such transport is robust for weak disorder in the cavity potential, strong disorder can lead to localization of light even under good thermalizing conditions.

We experimentally prove the feasibility of disordered quantum walks to realize a quantum simulator that is able to model general subdiffusive phenomena.
Our experiment simulates such phenomena by means of a finely controlled insertion of various levels of disorder during the evolution of the walker.
This allows us to explore the full range of subdiffusive behaviors, ranging from anomalous Anderson localization to normal diffusion.
